Question 1140695: Determine whether the infinite geometric series converges. If the series converges, determine the limit.
72 - 36 + 18 - 9 + ... Answer by Edwin McCravy(20056) (Show Source):
An infinite geometric series with common ratio r, |r| < 1 converges to .
a = first term = 72
r = common ratio = any term over previous term = -1/2
So it converges to
